12320,3D acceleration not working with Gnome Ubuntu 13.10 guest (falls back to software rendering),someguest,,"I have 64-bit Gnome Ubuntu 13.10 running in a VirtualBox 4.3.2 host (Windows 8.1 64-bit) with 4.3.2 guest additions installed by using the CD image that came with the host. Ubuntu's older guest addition packages are not installed (/usr/lib/xorg/modules/drivers/vboxvideo_drv.so is symlinked to /usr/lib/VBoxGuestAdditions/vboxvideo_drv_114.so, and /usr/lib/VBoxGuestAdditions is symlinked to /opt/VBoxGuestAdditions-4.3.2/lib/VBoxGuestAdditions).
According to Xorg.0.log (full log attached):
{{{
[ 24.027] (EE) AIGLX error: vboxvideo does not export required DRI extension
[ 24.028] (EE) AIGLX: reverting to software rendering
}}}
Needless to say, the guest desktop is terribly slow as a result of this. This has worked in older versions of Ubuntu (12.04 I think, with the bundled guest additions) and VirtualBox.",defect,reopened,major,3D support,VirtualBox 4.3.2,,,,Linux,other
